Optimal multi-objective VAr planning using an interactive satisfying method

In this paper, an interactive satisfying method, a two-level structure, is presented for solving a multiobjective power system VAr planning problem. In this structure, the analysis level is concerned with the calculation of a possible or it set of possible solutions to the multiobjective problem, and the decision level is concentrated on the task of inducing the analysis level to generate noninferior solutions that meet the decisionmakers' preferences. On the analysis level, the /spl epsiv/-constraint method based on the simulated annealing approach is developed to find a global noninferior solution. Through interaction with the decisionmaker, the proposed method guarantees the solution to be a desirable, global noninferior solution for a general multiobjective VAr planning problem. The presented method was applied to the AEP-14 bus system as well as to a large, actual-size system with satisfactory results.<
